Synthesis of bisfunctionalized unsymmetrical 2,2'-bipyridines 8 or their sulfonyl derivatives 12a,b are described. They were prepared via the Diels-Alder reaction of 1-methyl-4-pyrrolidin-1-yl-1,2,3,6-tetrahydropyridine (6) with 3,3'-bis(methyl- sulfanyl)-5,5'-bi-1,2,4-triazine (1). The reaction leads to the single cycloaddition product 7 which undergoes Diels-Alder reaction with cyclic enamine...

Straightforward palladium(II) catalyzed direct cross-coupling reaction between decyl, (S)-2-methyl-butyl, and dodecyl N-substituted diketopyrrolopyrrole thiophene (DPPT), including a 3-methoxy-thiophene derivative, 6-bromo-2,2′-bipyridine afforded series of mono- bis-bipyridine substituted DPPT ligands 1–3. Complexation reactions with PtCl2(DMSO)2 provided ortho-metalated platinum(II) complexes...

With the aim of improving the photoconversion efficiencies of heteroleptic [Cu(Lanchor)(Lancillary)](+) dyes in n-type dye-sensitized solar cells (DSCs), the previously favoured anchor ((6,6'-dimethyl-[2,2'-bipyridine]-4,4'-diyl)bis(4,1-phenylene))bis(phosphonic acid) (1) has been replaced by analogues 2 and 3 containing 2-thienyl spacers between the 2,2'-bipyridine metal-binding domain and the...

Reaction of AgPF(6) with the asymmetric ligand 1,6-dihydro-2-methyl-6-oxo-(3,4'-bipyridine)-5-carbonitrile (1), afforded a significant silver coordination polymer {[Ag(2)(1)(3)](2).(CH(3)OH)(3).(PF(6))(4)}(n) (2) with unique 1D twofold interpenetrating metal-organic frameworks constructed by 1D triple helical chains with nanosized cages hosting counterions as guests.
